Answer: A d=2.67
Explanation:
Simplifying
4.12 + -1d = 1.45
Solving
4.12 + -1d = 1.45
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add '-4.12' to each side of the equation.
4.12 + -4.12 + -1d = 1.45 + -4.12
Combine like terms: 4.12 + -4.12 = 0.00
0.00 + -1d = 1.45 + -4.12
-1d = 1.45 + -4.12
Combine like terms: 1.45 + -4.12 = -2.67
-1d = -2.67
Divide each side by '-1'.
d = 2.67
Simplifying
d = 2.67
